SPRING.

Application filed October 26, 1927. Serial No. 228,811.

My present invention relates to vehicle or suspension springs, and more particularly'to an improved spring suspension for automobiles and the like.

Vith the type of springs employed at the present day in automobiles, the easy and comfortable riding cannot be had unless the vehicle is equipped with shock absorbing devices and also the breakage of springs of the present day type is excessive, and the tempering of the springs appears to have no effect with regard to eliminating such breakage. I have, invmy present invention, devised a spring to obviate the objections to prior types of springs and have designed a spring which will act as a shock absorbing, as well as aspring suspending, device and in which the breakage will be reduced to a minimum. Further, in the present day types of springs, when a spring brealts, it is necessary to remove the entire spring assembly from either the front or rear axle and this operation seriously disturbs the setting of the means for clamping the spring pile-up on the axles. I have voided this feature in my present invention by the use of an im proved form of supporting chair for the springs and which supporting cha r, when once in position in connection witheither the front or rear axles, may remain so indefinitely and the springs associated therewith may be removed, replaced, or adjusted without in any way disturbing the adjustment of the chair with respect to the axles.

The object of my invention, therefore, is an improved spring for automobiles and the like.

In the accompanying drawings illustrating a preferred embodiment of my invention, and as applied to an automobile,

Fig. 1 is a sectional side elevation of the spring applied to a front axle;

l ig. 2 is a sectional side elevation of the spr or applied to a rear axle;

B1,, 3 is a side elevation of one of the spring units, and

Fig. 4 is a perspective View of the chair employed.

Referring to the drawings, and particularly to Figs. 1, 3, and 4, 1O designatesan open topped member, preferably a section of channel iron in which, on the closed face are cut-away portions 11, and adjacent such cut-away portions and in the side walls of the members are alined perforations 12 to receive bolts, as will be hereinafter described.

Also, and preferably centrally arranged with respect to the open side of the channel 10, is a wall or cross piece 1;), this member being preferably alined to the side walls of the channel 10 and providedwith a threaded perforation i i through which maypass an adjusting screw to be hereinafter described. The channel 10, as above described, constitutes practically a chair which rests on top of a front axle 15 or beneath the rear axle or housing 16 of an automobile. here the chair rests on the top ofthe front axle 15, U bolts 17 threaded at their ends to receive nuts 18 and utilizing a plate 19 are employed to clamp the chairlirmly on top of the front axle. In the case of the rear axle housing 16, achair piece 20 is placed between the upper face of the chair and the under portion of the axle pousing 16,and U-shapd bolts 21 are utilizet'in connection with nuts 22 and a plate 23 to hold the chair10 firmly in position beneath the rear axle housing.

Referring to Fig. 3, which represents one of the spring pile-ups, there is shown a: top leaf 2t formed with an eye 25 at one end and in which I may force a bushing 26. Be-

neath the leaf 2i. and associated therewith are a plurality of spring leaves 27 and also a spring lost 28 provided withan eye 29, at the end thereof remote from the eye 25 of tbeleaf 914:, and in this eye 29 is arranged preferably a bushing 30. The spring assembly comprised of the leaves 24-, 28 and the plurality of leaves 2'? are preferably held together by a rivet 31. Associated with the chair 10 are two of the spring assemblies illustrated in Fig. 3, and above described, and referring to Figs. 1 and 2, such spring assembly is shown with a bolt 33 passing through the perforations 12 and through the bushings in the spring leaf 28.

Referring now particularly to Fig. 1, the left hand spring pile-up of the type illustrated in Fig. 3 is shown with a bolt 34 pass-' the right hand spring assembly has a bolt 41 passing through the bushing 26 and through a spring shackle 42, pivotally attached by bolt 43 to the rear of the frame 35.

Resting on top of the pairs of spring assemblies of the type illustrated in Fig. 3 is a plate 44, which plate lies under the cross bar 13 and within the channel 10 of the chair. Threaded through the perforation 14 in the bar 13 is an adjusting screw 45 and by means of which the plate as may be forced into engagement with the free ends of the spring assemblies. The member 4 L may be of such dimensions as to be practically rigid as compared with the spring leaves or may be a length of spring material itself and, therefore, as resilient as the spring leaves themselves.

By referring to Figs. 1 and 2, it will be obvious that the weight on the end of the spring assemblies containing the bushing 26 will cause the spring assemblies to pivot about the bolts 33 and thus tend to force the free ends thereof upward and into engagement with the plate 3* Should, however, because of the automobile passing over a rough spot in the road, there be a relatively large movement of the frame 235 and the spring assemblies away from each other, the free ends of such spring assemblies will move away from the plate ll. and may possibly engage with the closed portion of the channel member 10, which will thus limit the movement and will act in a measure as a shock absorbing device.

lVhile I have necessarily shown and described a preferred embodiment of my invention somewhat in detail, it is to be understood that I may vary the size, shape, and arrangement of parts within wide limits without departing from the spirit of the invention.

Having thus described my invention, what I claim as new is:

1. In an improved spring, the eombination of a channel shaped chair, a pair of springs pivotally mounted in said chair, and having the associated ends of the springs within the chair separated from *ach other, means for engaging such ends, and means for adjusting the tension between said last named means and the separated ends of the springs.

2. In an improved spring, the combination of a channel shaped chair, means for permanently attaching the same to an axle of an automobile, a spring pivotally attached at one end of said chair and having one end thereof located within the chair, means at the other end of said spring for pivotally connecting the same to an automobile, and means for yieldingly engaging the end 01' the spring within the chair.

3. In an improved spring, the combination of a channel shaped chair adapted for pet manent attachment to the axle of an automobile, a pair of springs pivotally a ttaehed, one at each end of the channel shaped chair, and with the portions thereof within the chair separated from each other, means formed at the outer ends of each of said springs for pivotally attaching the same to an automobile frame, means for yieldingly engaging the ends of the springs within the chair, and means for adjusting the tension between said latter means and the ends 0 the springs.

In testimony whereof, I have signed my name to this specification.
